My invention relates'to-new and useful improvements in shot guns, and more particularly to the hammer mechanism therefor;

One of the objects of the present invention is to provide a shot gun, of either single or double barrel type, wherein, as a trigger is pulled, the hammer will not only strike the primer of the shell to fire the same, but it will slightly rebound, so that its'nose or firing point will not remain protruded through the plunger hole.

As is well known to those skilled in the art, or to those familiar with firearms, there is always provided, either a firing pin, or a hammer with a nose or firing pin formed integrally therewith, and those hammers-that have the firing pin integral with the hammer, or even those that have a separate. firing pin, often cause inconvenience to the shooter, for

the reason that after the gun: is fired, these firing pins, either the integral or separate type, remain protruded in the plungerholeso that the gun does not break open easily; This happens because the nose of the firing pin or nose of the hammer remains embedded-within the primer.

Still another object of theinventi-on, therefore, is to provide a shot gun wherein the hammer or hammers'are provided with anintegral firing point or nose, and wherein, when a hammer is released, its nose will strike-the primer of the shell and the hammer rebound, so that the nose will not project through the ,2 plunger hole, thus assuring an easy" breaking or opening of the gun at all times.

Still another object of the invention is to provide a shot gunwith a rebounding harnmer, and wherein the hammer springnot'only applies the striking force-to the hammer, but is also utilized to cause the rebounding action of the hammer.

Still another object of the. invention is to provide a shot gun with a rebounding hammer, wherein it is necessary only to provide an additional dog carried by the hammer, so hat the hammer spring acting on the dog will permit, or rather cause, thehammer to slightly rebound immediatelyafter striking the primer. I

Still another object of the invention "is-"to provide a shot gun 'which, of course;i'f ofthe double'barrel type, will have two rebounding hammers and'if of the single type, will have one rebounding hammer. I 1 At the outset, it might be mentionedthat the reboundinghammenas will'he explained, is especially adaptable, to the= Foxtype of gun, which type is Well known to" those familiar with shot uns. Still another object of the invention isteprovide a shot gun with rebounding harm mers, so that there is never any chance of the gun going off asthe gunis closed, which 0ccurrenee is not unusual in the ordinary-type ofgun, as should; the firing pin: or noseof' the hammer protrudethrough the plunger hole asthe gun is closed, it is apt to often strikelfiheprimer, and thus cause the prematurefi'ring, of'the gun. these and other objects in view,.the lnventlon consists in certain new and navel arrangements as will be hereinafter more fully'described and pointed out in the claims Referring now to the drawingsi'showing a preferred embodiment. ofzthe invention,

It also might be mentioned at this time, that I have not shown or described the looking mechanism for the gun, nor have I illustrated the safety device or the ejectors, as they form no part of the present invention, and may be of any type desired.

As may be seen in Fig. 1, there is shown a fragmentary portion ,1 of a fore-end, a part 2 of one of the barrels, in which there is a shell 3. There may also be seen a portion of the box frame at, whichfitsomai stock (not shown), there being the upper tang 5 and the locking lever 6. frame may be seen the plate Zwhich carries the trigger mechanism andwhose rear end forms a: tang 8. I Thebarrels are, of course, pivoted on the pin '9, and theremay be seen .theusual cocking slide 10 which will be forced rearwardly by the lug 11 when the gun is opened, as may be seen in Fig. 2.

..The parts so far enumerated are common to various types of shot guns, and need notbe de scrib ed morein detail.

both.

Now still referring to Fig. 1, there will be seen-mounted within the frame 4 a novel form of hammer 12, which is pivotally mounted ontlie pin. 13, which pin extends through the opposite sides of the frame 4. Of course, in

a double barrel shot gun, two of these hammersare used, as may be 56811 111 F g. 4, and a description of the one 1s a description of Nowbefore describing more in detail the hammer, there will be noticed a sear let pivoted as at 15 to engage the firing notch 16 of the hammer, this'sear, of course, being tripped b y the trigger 17, as may be seen in Fig. 1. I have not shown a safety lock on the tang 5, nor have I shown the locking bolt for the gun, .nor the ejectors, but it will be understood that any desired type may be used, as the present invention relates to the rebound ing hammersand their operation. Y

Now mounted in the forward end of the frame and referring to Figs. 1 and 2, there will be noticed the hammer spring 18, which fits within its chamber 19, while bearing against the spring is the little follower 20, which has the conical recess 21 formed therein. Likewise, it will be understood .that there will be one of these cocking springs, andfollowers, for each of the hammers in a double barrel gun.

' Still referring to Fig. 1, there will beseen the plunger hole22-in the plate 22', through which will pass'the integral nose or firing pin 28 of the hammer 12. x

Now referring more specifically to the hammer as shown in Figs. 5 to 5B V inclusive, this hammer is of irregular shape, having the upper portion 24 which is widened as at25 to provide the necessary weight, andis then narrowed as at 26, there being a second hole 27 extending through the hammer. It is to be noticed that thehammer is slotted as In the under portion-offbethat the hole 27' will pass through the opposite side walls of the slot. The hammer is then offset, as at 29, and is provided with the nose 30, which nose will be engaged by the cocking slide 10 when the said slide is forced slightly rearwardly when the gun is opened to cock the same. m Now where two hammers are used, one is a right and the other a left, so that they may be properly nested. (See Fig. 4

Now pivotally mounted within this slot 28 is the little dog 31 with its opening 32 so that this dog may be held by a pin 33 passed through the opening 7 27 in the hammer. This little dog has the little round pointed nose 31, is cut away in its enlarged rear as at 34; to partly encircle the pin 13 and rest against it when the hammer is in its extreme forwardmost position. The dog is slightly pointed as at 34'. Now the rear portion of the dog, that is, the pointed portion 34 will contact with the rear wall of the slot 28 in the hammer just below the pin 13 when the hammer is released, as shown in Fig. 1 of the drawings, to cause the same to rebound.

In Fig. 3 I have shown the far hammer 12 for clearness of illustration, and its sear 14. Likewise the cocking slide 10 and its cooperating spring 35 may be seen, and it will be understood that this cocking slide and spring are placed centrally of the tubes or barrels, and the frame 4, so that when the gun is opened, the cocking slide will project under the nose of each of the hammers and as the barrel is swung downwardly, the nose of the hammers will be forced upwardly to thus cause the two sears to engage the respective firing notches of the hammers.

Now as may be seen in Fig. 2, the little nose 31 of the dog fits within the recess 21 in the little follower 20, and likewise the far hammer will have its dog fitting within the follower of its cocking spring.

, Of course, there will be a scar spring 36 for each of the searsso that they will always immediately engage the firing notches of the respective hammers when the gun is broken to be cocked.

These sears in a double barrel gun, (as shown in Fig. 41), extend rearwardly and then inwardly as at 37 to be engaged or operated by the respective triggers.

Now the operation of the rebounding hammers (and describing the action of one) is as followsz Considering that the gun has been fired, the hammer 12 will now be in the position as shown in Fig. To cock the gun, the lever 6 will be released in the ordinary way, and the barrel moved downwardly to the positionshownin-Fig. 2. The cocking slide will be forced rearwardly a slight distance under the nose 30 of the hammer, as may be seen in dotted lines in Fig. 2, and asthe barrelis swung on the-pivot 9, it will force the hammer-to the position :shown-.r2,

of the dog 31. The nose of the sear will thenengage the firing notch :of-ithe hammer,

as may-- also be seenrin Fig.2. Now when the gun is Gl0Sed,':the hammer will-remain in the position as showniin Fig. '2,flont of course the cocking slide will again retract to its normalposition. 1 I 7 Now when the trigger 17 is manipulated, .thehammer spring bearingagainst the [dog 31 of the hammer, substantial-1y shown Fig. -1,, will cause the-hammer :(npper portion) to fly-forwardly the nose 23 will pass through the vplunger hole 22 to strike the primer ofthe cartridge. The dog :31 will have its rear portion strike against the hammer just above pivot pin 1.3., and :the pressure of the hammer spring bearing againstthe nose of the idogvmoiunted in the hammer, and the dog in turn striking' against the hammer just above the pin 1'3v will cause the hammer to rebound from the position shown in the dottedlines in'Fig ito the position shown in :fulll-ines, thus-preventing the nose 23 from remaining in a protruded position throughthe plunger hole.

Thus, it will be seen that the 'onteout portion eijbears against the pin 1 3 afterrthe hammer has been fired -which,iin ia'manner, limits the forward movement at the hammer, while on the firing, the upper end-534 ,ofthe dog will contact with the hammer just below the firing pin tocausea' slight rebound, as

clearly shown in Fig. 1. In other words,

the pointed nose 84 extends overthe @iYOtlZl pin for a sufficient distance to strike the hammer and to thus cause a slightneboundrofithe same. I

Therefore, when the lever 6 is moved and the gun is to be opened, :there is "110 possibil-ity of the nose 23 ofthe hammer iS'bil l projecting within the primer, thus assuring at all times that the gun maybe quickly broken to eject the 01d shell or shells and cock the gunto receive new Ones.

It will also be seen that there is no danger of the striking pin or'noseofthe hammer being protruded as the gu-n is'closeiwhich heretofore has often caused ithetiring of-the shell during the closing'action of the gun.

. It will also be seenthat this rebounding hammer mechanism is suitable for either a single barrel gun with the one hammer, :ora double barrel gun with the two hammers, and have illustratedthe double barrel gun 'just hammers and sears,

From the foregoing, it will be seenthat I have provided a gun with a rebounding hammer, wherein the hammer spring is utilizednot only {for the driving action of the hammer, but also for the I rebounding action of the hammer, Isothat it is .a simnlematter tononstt'notloreddtheimprovementnntlmed to;eeitaintypeszhf -gunsmominiuse,rit being only: neeessary h); ehange the nonstruetion oif the wand radid theitlittaei dogand: fol o-wer.
